Advantages and Disadvantages of DNA Fingerprinting - Essay Example

Due to a lot of base pairs the tasks of identification become very time-consuming so time-consuming why do scientists use repeating patterns in DNA?DNA profiling is used with D. It helps in the identification of identity with full confirmation (Brinton, K., & Lieberman, K). Scientists use the unique markers and m them up to form a peto It is useful in obtaining the identification needs and it also helps in providing information in case of missing people.

We can find out through the samples that they belong to one person, related people, or nonrelated people,e. Tnonrelatedrious forms of DNA fingerprinting which includes Southern Blot, through which scientists analyze the genetic pattern which is a part of a person’s DNA. In it the isolation of DNA from the rest of the cellular material is done followed by cutting the DNA into several pieces and then gel electrophoresis is done and finally the blotting of the DNA is done (National Health Museum).

Another kind of fingerprinting includes Restriction fragment polymorphism which analyzes the lengths of the strands of DNA. The polymerase chain reached polymerases in laboratories for hereditary authentication. Amplified fragment length polymorphism is also an important kind of fingerprinting. The most widely used kind of DNA fingerprinting is the short tandem repeat method which helps in extracting the DNA.

ADVANTAGES AND APPLICATION OF DNA FINGERPRINTING:

DNA fingerprinting helps in determining Paternity and maternity, as a person inherits the VNTRS from his mother and father that’s why it helps in finding biological parents. It also helps in finding personal identification. the fingerprints which are formed from the genetic bar codes help in identifying helphelpiduals.

It is very important in criminal suspects and criminal identifications. DNA material which is from blood, hair, skin cells, and other genetic proofs is available at the crime scene. DNA fingerprinting is thus helpful in finding criminals, guilty people, and innocent people. DNA fingerprinting also helps in testing for ethnicity. Overall tests are very helpful in finding deceased people's identification people's fits & limits of DNA Fingerprinting)
 

It is a very helpful method in finding bodies and identifications of soldiers who are killed in wars. It also helps in finding inherited disorders in newborn babies and prenatal babies.

DISADVANTAGES OF DNA FINGERPRINTING:

The fingerprinting process requires proper quality control methods and regulations along with proper standardization for it to be accepted universally. There are not many places and labs which can conduct the DNA fingerprinting process well, overall there are only a few proper labs that can provide accurate results for DNA fingerprinting. The probability of DNA sequence being similar is j one in 50 billion which is extremely low.

There is also a problem of population genetics as the genetic inheritance is not distributed evenly and they are not the same overall across human beings.

There are a few technical difficulties as well in DNA fingerprinting process, It is required to be run onis is various samples twice. There is another important disadvantage of the threat of the results being used for privacy concerns. Complete confidentiality is required and the information should not be shared with anyone except the owner.
